8 / 8 page REV. A –8– AD8015 AC COUPLED PHOTODIODE APPLICATION FOR IMPROVED DYNAMIC RANGE AC coupling the photodiode current input to the AD8015 (Fig- ure 17) extends fiber optic receiver overload by 3 dB while sacri- ficing only 1 dB of sensitivity (increasing receiver dynamic range by 2 dB). This application results in typical overload of –4 dBm, and typical sensitivity of –35 dBm. AC coupling the input also results in improved pulse width modulation performance. Careful attention to minimize parasitic capacitance at the AD8015 input (from the photodetector input), RAC and CAC are critical for sensitivity performance in this application. Note that CAC of 0.01 µF was chosen for a low frequency cutoff equal to 2.2 kHz.
